#""_6^13C# is isotope notation,
C-13 or carbon=13is hyphen notation

Explanation:

#""_6^13C# is isotope notation, atomic number (protons) left bottom, mass number (Protons + neutrons) upper left, then chemical symbol
#C-13# or Carbon-13 is hyphen notation, don't really need atomic number, because chemical symbol indicates it is carbon, so it must have 6 protons
